SSD & TRIM with OS X Capitan ?

[Fritzables]

Hi All,
I am about to install a new Samsung SSD (as the boot) on my 2011 iMac.
With this latest OS, are there TRIM considerations I need to be aware of?

Nope just drop in the SSD and go to terminal and enter "sudo trimforce enable" and your good to go. Make sure when you install your SSD you install the temperature sensor or your fans will fun at full speed all the time.

Hey satinsilverem2, thanks for that. Much appreciated.

Thanks satinsilverem2 - I'm doing the same thing but just wondering how do I install the temperature sensor you mentioned.

Thanks again Flyer

Though I dislike OWC, maybe this can help you.

I strongly advise against the Trim command. It may corrupt files on the SSD. GarbageControl is very good on modern SSDs and can be helped by leaving more free space on the SSD. There are even SSDs blocked in the Linux kernel:

The reason that Apple warns against the use of the trimforce command is not for nothing. Apple has their own controllers inside their SSDs.

The problem with TRIM and SSDs in Linux was traced to a bug in the Linux kernel. Apple does not use its own controllers in SSDs; there may be custom firmware, but the controllers are made by 3rd parties, such as Samsung and Sandisk.

Apple does not make the SSD controllers used in Apple branded SSDs. Third party manufacturer's do.

I have 5 internal SSDs in my cMP, all are Samsung, and a Transcend SSD in my MBA. I have been using TRIM since very early in the Yosemite OS life cycle. You are very wrong in your recommendation. And again, the problem is with Linux, not the Mac OS.

I highly recommend the use of TRIM, it is necessary for proper SSD maintenance.
